It is a term most commonly used in pornography. It is also referred to as Internal Ejacualtion. In anal cream pie's the male will usually plunge deeper into the anus and stay there until they're through cumming. Then they will slide there penis out slowly as to help the cum flow out of the anus. The female will sometimes squat or probe with their fingers to help gravity move the sperm. In vaginal cream pie's the guy will cum inside the vagina and pulls out their dick slowly and the female will contract their lower stomach muscles to push out the cum. Vaginal cream pie's are far more common than anal cream pie's.

Creampie, or internal cum shot, is a colloquial term in pornography to describe when a man ejaculates inside his partner's vagina. In pornography vaginal sex is generally followed by a facial or other visible ejaculation. This, coupled with the fact that the wearing of condoms for vaginal and anal intercourse is now commonplace in pornography -- whereas a creampie by its very nature cannot be accomplished while wearing a condom -- makes ejaculating in the vagina a novel situation which can be advertised to attract viewers.

An anal creampie (other terms: chocolate creampie, mudpie) is a variation where a man ejaculates in his partner's anus.
